INTRODUCTION
In this article I have provided an overview of the fascinating subject of "human life expectancy and longevity" and why it is probably going to increase more than you may expect. If you are over 50, this article has important information for you
This subject is vast and its implications for humanity, at both the individual and collective level, are huge. This article will set the scene for a series of articles that will explain in more detail, what is happening, why it's happening, what it will mean for you and how you can make sure you are fully prepared to take advantage of the opportunities that will be available to maximise your personal longer healthier life.
THE LONGEVITY REVOLUTION
I believe we are very fortunate, as mature people in a developed nation, to be living at such an exciting time. The Longevity Revolution is upon us and it offers hope, even an expectation that we can all look forward to the possibility of a much longer healthier life than we could have even conceived of as recently as 15 years ago. This new field of study and research is being referred to as "Life Extension."
The longevity revolution is already happening in biotechnology and medical science, and is going to result in a quantum leap in our lifespan; but even more importantly in how long we will stay healthy i.e. our "healthspan".
Right now, longevity statistics tell us that average life expectancy at birth in the top 20 ranking nations is 80 years; but of that on average, the last 8 years (10%) is spent in ill health.
To extend our lifespan without improving our healthspan would be pointless, maybe even cruel, and would place even greater pressure on our social security systems and national budgets, at a time when the ever increasing population of people over 65 is already threatening to swamp them.
HUMAN LONGEVITY-THE LAST 100 YEARS
Before we look into the crystal ball and attempt to see into the future, let's briefly review the recent history of longevity and current predicted life expectancy statistics.
"Life expectancy," according to the World Health Organisation website, is "the average number of years a person can expect to live, if in the future they experience the current "age-specific" mortality rates in the population." In other words, no significant changes occur in the person's lifetime; either positive or negative.
In the last 100 years, life expectancy in Developed Nations has increased by 50% from 53. 6 years to 80.4 years. This has been due to a combination of two factors; a reduction in child mortality and older people living longer.
In his article "Broken Limits to Life Expectancy" in "Science" magazine in May 2002, Demographer James Oppen stated "For 160 years, best-performance life expectancy has steadily increased by a quarter of a year per year, an extraordinary constancy of human achievement."
The main reasons for this massive increase have been:
- Advances in food supply and nutrition,
- Vastly improved sanitation and hygiene,
- Clean drinking water,
- Technological breakthroughs,
- The advent of major new medical technologies and medicines (e.g. antibiotics),
- Better housing, including clean heating systems (i.e. replacing coal fires), and
- Increased awareness and knowledge about the importance of a healthy lifestyle.
THE FUTURE-WHERE TOO FROM HERE?
Many longevity scientists believe that over the next 10 years there will be dramatic advances in biotechnology that will radically change the future prospects for longevity from which we can all potentially expect a significant increase in life expectancy. There is widespread belief that an average life expectancy of 100 years is possible in developed nations in that timeframe.
So taking action right now in all the key areas of your lifestyle will increase your chances of being around to take advantage of these imminent benefits.
My research suggests that there are 4 areas for continuing research, development and public education that must be addressed simultaneously, and with urgency if as many of us as possible are to reap the full benefits that will be available:
1. Continuing the great work being carried out by Medical institutes and public health professionals across the globe to combat these chronic degenerative diseases This work has already saved many lives and improved the lives of many others, and it needs to continue.
2. Continue to educate people; that contracting these chronic diseases as they age is not an inevitability, and that they can significantly reduce the risks of contracting them by leading a healthy lifestyle i.e. adopting a healthy anti aging diet and avoiding the unhealthy foods and ingredients that damage their health, by avoiding unhealthy addictions, by a regular exercise and fitness practice and by reducing the stress that weakens the body's immune system and invites these diseases in.
3. In his fascinating article "A Wrinkle in Time" Stuart Jay Olshansky, a Professor in the School of Public Health at the University of Illinois, Chicago made the following statement:- "Scientific evidence now strongly supports the idea that it's time to invest in the future of humanity by encouraging the commensurate political will, public support, and resources required to slow aging, and to do so now, so that most people currently alive might benefit from the investment." and that "there is ample reason to be optimistic that decelerated aging can be achieved for humans."
4. As I said in the introduction, the longevity revolution is already happening in biotechnology and medical science, and is going to result in a quantum leap in our lifespans, but even more importantly, in how long we will stay healthy.
What would have been considered science fiction 20 years ago is now becoming a reality. The human genome project, completed in 2003, has opened up a multitude of amazing possibilities. The new field of "tissue engineering" is enabling medical laboratories to create replacement body parts and organs using an individual's own cells, and work already underway includes growing new organs, breast tissue, windpipes and bladders, amongst many other body parts.
CONCLUSION
Over the next 10 years, major advances in biotechnology will radically change our future prospects for longevity from which we can all potentially expect a significant increase in life expectancy. There is widespread belief that an average life expectancy of 100 years is possible in developed nations in that timeframe.
By taking action right now in all the key areas of your lifestyle, you can increase your chances of being around to take advantage of these imminent benefits and live a much longer, healthier and happier life.
